    CATEGORY OF LYRICISM IN THE PROSE OF I.A. BUNIN (LINGUO-POETHICAL ASPECT)

    No full text
    The article is based on linguistic poetics and devoted to clarifying category of lyricism which forms style of Ivan Alekseyevich Bunin’s prose. In prose of this author appear many features like instance musicality, poetizing of depicted reality, subjectivity, weaken of the narrative, realized by the means of certain phonetic and lexical methods

    Kawaguchi-Silverman conjecture on automorphisms of projective threefolds

    No full text
    Under the framework of dynamics on normal projective varieties by Kawamata, Nakayama and Zhang \cite{Kawamata85,Nakayama10,NZ09,NZ10,Zhang16}, Hu and the author \cite{HL21}, we may reduce Kawaguchi-Silverman conjecture for automorphisms ff on normal projective threefolds XX with either the canonical divisor KXK_X is trivial or negative Kodaira dimension to the following two case: (i) ff is a primitively automorphism of a weak Calabi-Yau threefold (ii) XX is a rationally connected threefold. And we prove Kawaguchi-Silverman conjecture is true for automorphisms of normal projective varieties XX with the irregularity q(X)dimX1q(X)\ge\dim X-1. Finally, we discuss Kawaguchi-Silverman conjecture on normal projective varieties with Picard number two.Comment: 16 pages, thanks the referee for useful comments, accepted by International Journal of Mathematics. arXiv admin note: text overlap with arXiv:2208.0261

    Engaging the online audience in the digital era: A multimodal analysis of engagement strategies in TED talk videos

    No full text
    Scientific popularization genres have attracted the attention of researchers in esp. Authors of such genres have been found to employ a variety of strategies to engage the readers. However, most studies of engagement in scientific popularization tend to focus on written genres. For this reason, they have mostly examined only the linguistic mode and rarely gone beyond this to take multimodal resources into consideration. the present study investigates how multimodal semiotic resources are combined in digital media to engage the online audience in an influential online scientific popularization genre, that is, TED talks. drawing on a corpus of 28 highly viewed TED talks from the area of biology, this study provides an in-depth analysis of multimodal engagement strategies in one of those talks. the analysis shows that the engagement of online viewers in a digitally mediated scientific popularization genre like TED talks tends to be achieved by the combination of multiple semiotic resources afforded by digital technologies, such as speech, gestures, gaze, visuals, distance of shot, perspective of shot and angle of shot. the study also reveals five strategic multimodal configurations employed to achieve viewer engagement, with the focus variously on engagement through visual aids, a long shot, gaze, questions and reference to personal emotionsLos géneros de divulgación científica han captado la atención de los investigadores del ámbito del inglés con fines específicos. Se ha constatado que los autores de tales géneros emplean diferentes estrategias para involucrar al lector. Sin embargo, la mayoría de los estudios sobre la noción de implicación (engagement, en la bibliografía anglófona) en la divulgación científica se han centrado en los géneros escritos. Por ello, hasta el momento se ha analizado fundamentalmente el modo lingüístico y apenas se han explorado otras áreas como los recursos multimodales. El presente artículo analiza el modo en que se combinan los recursos semióticos multimodales en los medios digitales para implicar a la audiencia en línea en un influyente género de divulgación científica en Internet: las charlas de tEd. El análisis llevado a cabo muestra que es una combinación de múltiples recursos semióticos posibilitados por las tecnologías digitales aquello que permite implicar a la audiencia en línea en un género de divulgación científica digital como las charlas de tEd. Entre esos recursos se encuentran el propio discurso, los gestos, la mirada, los elementos visuales o la distancia, la perspectiva y el ángulo de la toma. Este trabajo también formula cinco configuraciones multimodales empleadas estratégicamente para involucrar a la audiencia, con especial atención al uso de elementos visuales auxiliares, planos largos, miradas, preguntas y referencias a las emociones personale

    A History-Based Matching Approach to Identification of Framework Evolution

    No full text
    In practice, it is common that a framework and its client programs evolve simultaneously. Thus, developers of client programs may need to migrate their programs to the new release of the framework when the framework evolves. As framework developers can hardly always guarantee backward compatibility during the evolution of a framework, migration of its client program is often time-consuming and error-prone. To facilitate this migration, researchers have proposed two categories of approaches to identification of framework evolution: operation-based approaches and matching-based approaches. To overcome the main limitations of the two categories of approaches, we propose a novel approach named HiMa, which is based on matching each pair of consecutive revisions recorded in the evolution history of the framework and aggregating revision-level rules to obtain framework-evolution rules. We implemented our HiMa approach as an Eclipse plug-in targeting at frameworks written in Java using SVN as the version-control system. We further performed an experimental study on HiMa together with a state-of-art approach named AURA using six tasks based on three subject Java frameworks. Our experimental results demonstrate that HiMa achieves higher precision and higher recall than AURA in most circumstances and is never inferior to AURA in terms of precision and recall in any circumstances, although HiMa is computationally more costly than AURA.Computer Science, Software EngineeringEngineering, Electrical & ElectronicEICPCI-S(ISTP)

    L-Cysteine-Modified Acacia Gum as a Multifunctional Binder for Lithium-Sulfur Batteries

    No full text
    A binder plays an important role in stabilizing the electrode structure and improving the cyclic stability of batteries. However, the traditional binders are no longer satisfactory in lithium-sulfur (Li-S) batteries because of their failure in accommodating the large volume changes of sulfur and trapping soluble intermediate polysulfides, thus causing severe capacity decay. In this work, we prepared a multifunctional binder for Li-S batteries by merely modifying the acacia gum (AG), a low-cost biomass polymer, with L-cysteine under mild conditions. Owing to the introduced amino and carboxyl branches by the L-cysteine, the modified AG shows enhanced polysulfide trapping ability and can effectively restrain the shuttling of polysulfides. In addition, the introduction of branches can help form a cross-linked 3D network with better mechanical strength and flexibility for adhering sulfur and accommodating the volume changes of cathode materials. As a result, compared with the normally used polyvinylidene fluoride binder and the unmodified AG binder, the L-cysteine-modified AG binder effectively enhanced the rate capability and cycling stability of the Li-S batteries directly using sulfur as the cathode, showing a promising way to prompt the practical use of Li-S batteries
